Range Breakout AFL Strategy


Step 1: The Trading Idea

Buy or Sell when prices break the range of previous n periods

Step 2: Selecting Indicators for Trading System

This strategy uses only price action and no indicators. The range for last n periods is calculated by taking the highest high and lowest low value of last n periods. This range is also called Donchian Channels.

Such trading strategy was suggested by trader Richard Donchian. Richard suggested to use the strategy on daily timeframe for a range of last 20 days. In our testing on 15-minute time frame, we use the 50 period window to avoid false signals.

These are also called volatility bands because the expanding/contracting channels indicate the market volatility. The trading rules for this strategy are similar to the ATR Bands Strategy and Bollinger Bands Strategy.

Step 3: Defining Clear Rules for Range Breakout AFL Strategy

Buy: When price cross above the 50 period range

Sell:  When prices cross below the 50 period range
